The Clone Wars REALLY nailed the aesthetic when it came to starships. The only thing that honestly looked at all cartoonish were the characters. Any tech looked pretty real in star wars terms. As a result, I can generally buy into TCW giving accurate proportions for starships and other technology. Love it or hate it, it is at least an impressive looking show.
Quite so.
I have been watching it lately, and, yes, the way the characters are drawn are the second-most annoying thing about it. The most annoying thing about the show is how some of the characters behave. I was just watching a few episodes from season 5 in which a group of droids goes on an infiltration and retrieve mission. The astromechs were largely fine, but the way the speaking droids largely behave is beyond comprehension.
But, we're talking about the way the ships and stuff look, and I'll grant you that that all looks pretty good. Also, I think your argument of recent evidence having some greater weight is not too shabby. What I object to is calling it "proof" in size-24 font. I'm a scientist (of sorts), and 'proof' is not a word I would use lightly.
Especially in a fictional world in which any person at Disney aside from the janitor can change it all up at a whim.
